Application filed February 23, 1910, Serial No. 545,407. Renewed March 11, 1911. Serial No. 613,848.

To all whom it may concern:

Be it known that I, CLARENCE CosBY, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Can-Shearing Machines, of which the following is a specification.

This invention relates to automatic shearing machines for shearing the heads or ends of cans, and for flattening and cleaning the sheets forming the bodies of the cans after shearing, to make said sheets available for further industrial purposes.

The object of the present invention is first, to provide means for cutting out the heads of the cans; second, for cutting out the'side seam of the cans; and third, for cutting off the head seams and flattening and cleaning the body sheets.

The invention is illustrated in the accompanying drawings in which Figure 1 is a side elevation, partly in section, of the machine. Fig. 2 is an end elevation thereof. Fig. 3 is a detail in side elevation of the mandrel and associated devices which cuts out the heads of the cans and also cuts out the longitudinal or body seam. Fig. 4 is a detail in longitudinal section of the parts shown in Fig. 3. Fig. 5 is a section of the same on the line 55 of Fig. 3. Fig. 6 is a view of the mandrel. Fig. 7 is a detail in end view of the track on which the can carriers travel. Figs. 8 and 9 are details in section of the stripping devices. Figs. 10 and 11 are details in section of parts of the mandrel. Figs. 12, 13 and 14 are details in end, side and sectional views of a modified form of mandrel.

The base of the machine is indicated at A, with two side frames B mounted thereon, and these side frames have bearings C at opposite ends which carry the cross shafts E provided with sprockets F around which passes a chain belt G which carries a series of can carriers or buckets H fastened thereto. Behind each bucket the chain carries a fixed arm J with a spring finger K pivoted to the outer end thereof.

The shafts E are driven by means of bevel gears 30 on the main shaft N which will be driven by means of a belt on pulley R, and

which carries a fly wheel Q, and is supported by pedestals O on the base. The boxes for one of the shafts E may be set up by screws 12, to take up any slack in the chain.

Mounted upon the side frames B is a continuous track consisting of two opposite corresponding rails 11, conveniently made of angle metal. The buckets or can carriers H travel on this track, the runs of the chain being parallel to those of the track, and the chain being located in a position between the opposite rails. Each bucket or can carrier consists of a base member h and two side members it, hinged at 7& to the sides of the base member, which latter is fastened to one of the links of-the chain. Each section it of the bucket or carrier has a lug [L which hooks over the flange 11 of the track, and. the hooked lugs serve to open or close the buckets, according to the lateral variation in the line of the rails with respect to the line of the chain. The rails approach each other as indicated at 11 which is the place where the cans are received by the carriers from the chute 19. At the opposite end of the top run of the track the rails diverge and incline downwardly, as indicated at 11, which is the place where the cans are released from the carriers, as more fully hereinafter explained, the efiect of the irregular lines of the rails being to close and open the carriers at desired points, to grip or release the cans, by means of movement of the hinged sections it of the carriers. The chain travels with its upper run moving to the right, in Fig. 1, and by means to be described the cans are fed one by one to the carriers and the cans travel endwise with the carriers along the track, and while they are so carried the heads are cut out and also the longitudinal seam.

For cutting out the heads of the cans as they are carried along the following means are provided: 41 is a mandrel which is supported and extends lengthwise between the upper runs of the track rails and above the upper run of the chain 11, and in the line of travel of the carriers. At the front end this mandrel has a plurality of pointed blades 42 fastened by screws 70 to a plunger 72 the stem 73 of which works in an axial bore in the front end of the mandrel. The head 7 2 also carries an ejecting plunger 13 provided with a stem 130 which slides in an axial bore in the head 72. The plunger 13 is normally extended with its head between the shear bladesby means of a spring 131, and the stem is provided with a notch 132 arrangedfor engagement by the edge 140 of a latch 14 which works transversely in a suitable recess inthe head 72 and is arranged to be engaged and pressed in by the forward edge of a'can as the can is carried over the mandrel. Screwed on a reduced portion at the front end of the mandrel is a ring 82, and a spring 16 is coiled around the head 72 between a shoulder 74 on said head and the front end of the ring. 'The stem 73 of the head has an inclined groove at5 which receives the point of a screw 76. I Mounted upon the mandrel behind the ring 82 is a sleeve 83 which is slidable lengthwise on the mandrel, .and attached to this sleeve are arms or rods 84 which travel in longitudinal slots 85 in the mandrel, A spring 86 is coiled around the mandrel between the sleeve 83 and a shoulder 87, and the purpose of this spring is to normally hold the sleeve in advanced position and to return it after it is pushed back on the mandrel as hereinafter described. The sleeve 83 carries catches 88 working in recesses in said sleeve and having points projecting beyond the surface of a the sleeve in position to be struck by the 7 side pieces h of the can carriers as the latter travel with the can along the mandrel. The sleeve 83 has semi-circular slots 89, on opposite sides thereof, and through each slot projects a pin 90 the inner end of which is mounted and travels in one of a pair of spiral slots 91 which extend from the bottom or underside of the mandrel and upwardly and backwardly on opposite sides of the mandrel. The mandrel has recesses 92 in position to allow the catches 88 to drop into the same when the sleeve 83 is pushed back to its extreme rear position. The rear ends of the arms 84 carry pivoted latches 93. The grooves 85 terminate in openings 94, with a curved back wall 95 and an inner shoulder 96. When the sleeve 83 is pushed back the ends of the fingers 93 strike the wall 95 and are turned up to project out" through the openings 94, and the heel 97 of the finger catches on the ledge or shoulder 96, acting as a latch to prevent the forward movement of the sleeve 83 until the projecting ends of the fingers 93 are struck by the advancing carrier and released by pressing the same backwardly until the heels 97 disengage f-rom the shoulders 96, when the sleeve and parts carried thereby are returned by the spring 86. The operation of the parts just described is as follows: As indicated above, a can is grasped by the carrier jaws and is forced against the ends of the blades 42 which penetrate the front end or the head of the can and begin to out the same out.

When the head of the can strikes the plungerhead 13 it forces the plunger backwardly against the tension of the spring 131 into the mandrel head, and when it reaches its limit of movement the notch 132 is engaged by the edge 140 of the catch 14, in consequence of the pressure of the spring 141, and the plunger is held in this position until the forward end of the can comes in contact with the exposed beveled end of the catch 14, and as the can is carried along it forces said catch inwardly, thereby releasing the plunger stem, and the spring 131 expands and clears the shear blades of the scrap or cut out head, said head having meanwhile been cut out by the advance of the can. While this action is taking place the coiled spring 16 is compressed, permitting the plunger head 72 to be forced back slightly, and in consequence of the engagement of the screw 76 in the inclined groove 75 the head 72 is turned slightly, thus turning the blades 42 and insuring a clean cut. The same action takes place when the rear or other head of the can reaches the shear blades, and both heads are thereby cut out of the can and ejected by the action of the plunger 13. The can body is then in tubular condition with a'slight rim at each end, and it is thus carried along until the front edge of the carrier sections it strike the ends of the catches 88, and in consequence of the advance of the carrier the sleeve 83 is slid back along the mandrel. As the sleeve moves it carries with it the pins 90 and said pins have a turning movement around the mandrel in the slots 89 in consequence of the shape of the grooves 91. As the pins travel along the spiral grooves one or the other will come in contact with the longitudinal seam of the can, or with the ridge produced thereby on the inside of the can at the seam, said ridge being made by the lap of the seam on the inside of the can. Obviously the longitudinal seam may be located in any position around the mandrel, and hence it is necessary to provide two grooves and two pins so that if it happens to be on one side of the mandrel it will be caught by one pin, or on the opposite side of the mandrel by the other pin. As the appropriate pin 90 travels around inside the can it is pressed in contact therewith by the spring 90 and sooner or later will strike the seam, and when it does this it will carry the can with it, that is, the can, in addition to its forward movement along the mandrel, will havea turning movement incident to the engagement of the pin 90 with the seam, and finally will be turned so that the seam will lie along the top of the mandrel, at which time the pins will reach the ends of the respective grooves 91, which are there deepened to allow the pins to retract from the can, and the can will advance with the longitudinal seam, as stated, directly along the top of the mandrel. Meanwhile, the fingers 93 at the ends of the arms 84 will have been caught at the ends of the grooves 85, as above described and the sleeve 83 will be held, the catches 88 dropping in the recesses 92 to allow the can to pass along, and when the fingers 93 are struck by the advancing carrier the release is effected as above described and the spring 86 will expand and force the sleeve back to original position for operation on the next can. In order, then, to cut out the longitudinal seam of the can as it is advanced along the mandrel, a pair of cutters 10 is provided, cooperating with a shear roller 19 set in a recess in the mandrel, this roller being directly in line with the ends of the slots 91, so that the seam will pass across the roller, and the cutters 10 cooperating wit-h said roller will shear the can on opposite sides of the seam, and so cut out the seam which will drop off into scrap.

The mandrel is supported by means of a web 22 depending from angle brackets 20 .fastened to the frames B, and said web is located in line with the slot produced by cutting out the longitudinal seam. It is desirable to spread the slot somewhat, and for this purpose the web is sharpened at the front end as indicated at 22 The rotary shears 10 may be driven by any suitable means. I have illustrated a bevel gear 10 on the shaft N which meshes with a bevel gear 10 on a cross shaft 10 which is connected by bevel gears to a vertical shaft 10 which has at the upper end a bevel gear meshing with a bevel gear on the shaft of the cutters 10. After the can passes the shears 10 it is carried along the mandrel in the carrier H, and the track then drops and spreads slightly as indicated at 11, and the can is finally pushed off the rear end of the mandrel onto a roll 8 which is mounted on a shaft 3 driven by gears P and S from the main shaft N, the shaft 3 being mounted in bearings in the pedestals I and Z. The can is effectively pushed off the mandrel and onto the roll 8 by means of the fingers K which engage behind the end of the can, the carriers H meanwhile opening in consequence of the spread of the rails at that point. The fingers K are carried by the arms J projecting from the chain and as the chain travels the fingers advance and push the can onto the roll, the fingers finally yielding in consequence of springs at 72, coiled around their pivots, thereby permitting the fingers to slip by the end of the can body on the roller 8, which is beveled at its front end, as indicated at 8*, to let the can on.

Cooperating with the roll 8 is a roll 6 mounted on a shaft 4, the boxes 4 of which are slidable up and down in guides 4 in the pedestals. The shaft 4 and the roller 6 carried thereby are raised and lowered in proper time by means of an eccentric 100 on the shaft N which operates a lever 101 pivoted at 2 on the pedestals and connected by a link Y to said shaft 4. The eccentric is properly constructed to lift the roller 6 from the roller 8 while the can is being placed on the latter and to then drop to contact with the can body which is thus gripped between the rollers 6 and 8.

A stripper 102 is provided for the purpose of stripping the can body from the roll 8. It consists of a curved plate supported by the frame 13 and located with its edge in contact with said roll 8. As the can body turns with the roll 8 the said edge 103 of the stripper plate enters under the can body, through the longitudinal slit therein, and strips the same from the roll. Said stripper plate has curved side edges 104, and as the can body is forced over the plate it is somewhat flattened, its edges engaging under the curved flanges 104 to hold it to the plate. From the plate it passes between shear rollers 7 and W, the former being mounted on a shaft 5 driven by gears T and V from the shaft 3. Said roller 7 is provided at opposite ends with shear blades 7 which cooperate with the ends of the roll W to shear off the rims or corner seams at the ends of the can body. From these shearing rolls the body passes to a train of rolls and brushes 15 and 16 mounted in the frame, said train being substantially identical with that shown in my pending application No. 520704, for the purpose of flattening and cleaning the body plates which pass between the rolls in the manner described in my said application and are finally delivered therefrom.

For feeding the cans to the carriers H chute 19 is provided. The cans slide down this chute endwise, and they are dropped out one by one by means of a hinged leaf 32 at the lower end of the chute, the hinge being indicated at 31. This leaf is operated by a lever 26 which is fulcrumed at 33 and connected by a link 27, lever 28, link 29 and lever 31 to the leaf. The front end of the lever 26 projects into the path of the carriers H. When a carrier strikes said lever it lifts the same and lowers the leaf32, allowing a can to slide down endwise into the carrier which is then approaching at a corresponding inclination along the forward curve of the track 11, and being gradually closed to grip said can as it passes between the aws of the carrier. Succeeding cans in the chute are meanwhile stopped by means of a yoke 50 fastened to the inner end of a rod 51 which telescopes in a sleeve 52 and is held in place by a pin working in a slot 53, with a coiled spring 54 between the yoke and the sleeve. When the upper end of the lever 26 swings down the yoke strikes or presses upon the second can in the chute and holds the same while the first can drops into the carrier, and when the lever 26 passes oif the'carrier the lever returns to its normal po sition and the yoke is lifted to release the line of cans for the next operation.

Recapitulating the operation of the machine, it may be said that the cans are fed from the chute 19 into the carriers and travel therewith around the track, and while so carried the heads are cut out by the blades 42 on the front end of the mandrel 41, the scrap heads being ejected by the plunger 13, after which the can bodies are positioned by the pins 90 to bring the longitudinal seams of the cans on top of the mandrel, where they are cut out by the cutters 10, after which the bodies are carried along and placed on the roll 8 from which they are stripped by the stripper 102, whence they pass to the shear roll 7 to cut off the ends or corners of the body, after which they pass through the cleaning rolls, leaving the body sheets in clean condition for commercial use.

The invention is not limited to the exact mechanism shown, and no limitation in this respect is implied. The mandrel above described is suitable for round cans. Inasmuch as cans are sometimes square or otherwise angular in shape, in Figs. 8, 9 and 10 I show a modification in which the cutters 42 of the mandrel are arranged in rectangular position at the end of the mandrel. These operate to cut out the can heads as above described. To then press the angles out of the can bodies I provide a pair of rollers 120 which cooperate with a roller 121 located on the mandrel behind the blades 42*. The diameter of this roller 121 is notgreater than the shortest diameter of the cutting head, and after the can body passes the cutter head and between the rollers 120 and 121 the latter are dropped to contact therewith, being carried at the end of a lever 122 fulcrumed at 123 on a suitable frame and operated by any suitable timing mechanism to be pressed to contact with the can body which will then be spun around between the rollers 120 and 121 and flattened as it passes along the mandrel. While it is spinning or rotating on the mandrel the longitudinal seam is found and located at the top line of the mandrel by one or the other of the seam finders 124 and 125. The former consists of a finger projecting from an extension of the lever 122 in position to rest upon the outside of the can. The latter consists of a spring finger located in a recess in the mandrel and arranged to press against the inner surface of the can body, and as the can comes around one or the other of these'finders" will strikethe longitudinal seam and thus stop the turn of the can with the seam at the upper position, or on top of the mandrel, after which the body. will be carried along to the shears 10 and 19 for further operation as above described. For oblong cans or cans of other shapes the shape of the head 4C2" may be varied accordingly.
